Error: Package: teamviewer-15.4.4445-0.x86_64 (/teamviewer_15.4.4445.x86_64)
Requires: libc.so.6(GLIBC_2.17)(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
thanks

The answer is the same if the error is the same and there is nothing that we can do to fix it. The error you posted is saying that the glibc version on your system is too old to work with the application and you cannot update glibc so the app has to change.

The warning about CentOS 6 dying in November is even more true for 6.8 which is already 4 *years* out of date and riddled with security vulnerabilities.
